The Schedule referred 'to in these Letters Patent and making part of the camz.

flfo all Awhom it may concern:

Be it known that I,WILL1AM H. PALMER, Jr., of Middletown, in the county of Middlese, in the State Y of Connecticut, have invented certain new and useful Improvements in Machines forManufactuiing Gord,

. Gimp, Snc.; and I do hereby declare that the following is a full and exact description thereof.

My invention is more especially intended for tho manufacture of picture-cord, and the like, or ornamental cord, in which the strands'are wound or served .with

silk or worsted, to impart an ornamental nish; but i parts of my invention may be used with success:V in

the manufacture of gimp, so covered, by which l mean single strands, not twisted or held together, and also in the manufacture oi' cords, composed of twisted or laid strands not covered.

Irwill first proceed to describe what l consider the` best means of carrying out my invention, and-will afterwardsdesignate the points which 1 belieye to be new.

The accompanying' drawings. form a part of this.

` specification.

Figure lis a side elevation of the machine complete;

Figure 2 is a plan xiew of a portion of the machine;

Figure 3-is a vertical section, through a portion, on a. larger scale;

Figure 4isa longitudinal section on the lineS S in tig. 3;

Figure 5 is a plan view of the belt and pulleys,- which'diive the covering-1uechanism; and l Figure 6 is a correspoiuling view 'of the belt and pulleys which drivethc cord-mechanism.

Similar letters of reference indicate like parts .in all the figures.'

The drawings represent the novel parts, with so -much of the other palts as isncccssary'to indicate their relation thereto.

.Tints are employed mainly to'aid in distinguishing parts, and do not indicate material. 1

The material of the entire machine may he iron and steel.v 1

The fibrous material employed may be of any color.

It is usual to employ a coarse and unattractive materialaS-hemmjute, or the like, for the inncr lmatei ofeach strand,'and brilliantly-colorcd material, as scarlet, or blue silk, or worsted, for the covering-mate- A is the frame-work, made of cast-iron, or other suitablemateria-l, and, adapted to support the several parts firmlyT and providing 'suitable bearings for the journals.

,-B is an upright'shahstepped in the trame-work A, at the bottom, and extending upward `more than half 'wayto thetop inthe-machine, carries a bevel gear-wheel, B, which receives .a constant rotatory niotion from a corresponding bevel-gear wheel, Gl, on the di'ivingshait C, whichllatter is impellcd by a steamengine, or other suitable power, through a belt or other connection not represented.

D is a frame-work, adapted to carry the bobbinsand other main parts .ofthe mechanism to be described hereafter. lo it is fixed the bevel-gear wheel D, which meshes also into the driving-gear wheel G, so as to impart a rotatory motion to the amefwork-D, in a direction opposite to that of the interior shalt B. The weight of the revolving frame-work D, and' its `connections, rests on dollars on the internal shaft B, and it is steadied entirely thereby.

" At the top it is sustained in a' bearing on theframe work A, this healing being formed at the point, where a `lay-block is introduced into the interior of the bearing, through which the strands issue, an are laid together with a proper twist.

It will be understood that by this arrangement, the internal shaft Band its connections, and the frame-work D and its connections, revolve in `opposite directions. k'ii1e"1neehanism` above mentioned for taking away-and dinary character, and need not be specially described.

This material g forms the body or mainsubstancc of each .strand ofthe cord, gimp, or whatever is being manufactured. This material, g, is led from th'e spools G, through the eye G, up over the hook or peg G6, down again and partially around the shaft G, to pass under the hook or peg G7, thence upward through and in the hole G8, into the hollow interior of the upper end of the shaft G. t

It will be understood that'the friction of the spools or bobbins G, and the friction induced by the passage of the material, y, through'tlie guide, and around the pegs, as represented, induces a sutlicient resistance to give a proper tension or draught of the material as it is drawn otili'n the manufacture of a cord.

A hole is made in the trame-work D, directly in line with the centre of each spindleG, of` suliicient size to allow the material, g, to be led upward through it to be covered above, 'as will be presen'tly described.-

The central upright shaft B carries two pulleys, of didi-freut sizes, B" and B3. These are made in a single pieccfand 'dried ou the shaft B by means of the pinchingscrew b, so that they may be adjusted up and down as required. These pulleys impait a rotatory ranged thereon, as represented. This belt may be changed from the pulley BZ to the pulley Ba at pleas nre, and in such case the pulleys B and B*l are moved reeling ,the cord as fast as it is produced, is of the or-` G G, &c., `are upright shafts, mounted in the framcresented.' 'I hey` carry, near their lower ends, pulleys motion in the same direction to the several pulleysn "G and their connections, by means of the belt M araerial n are 'mounted with their axes in a plane an righil angles to the axis of motion, instead of parallel thereto,- as represented, allows me, while mounting the eover- A ing-eye D very low, to draw the strand therefrom at the greatangle represented, and avoid a necessity for extending it a great way up, and thus making the machine Eqf inconvenient dimensions.

` This' arrangement also .insures a greater uniformity in the manner iu which the covering-material. is applied, because, if the bobbins stood upright, or parallel to the axis of rotation, the stui, drawn first from one -end and then from the other of each bobbin, would not the mechanism, substantially as 'sndfor the 'purpose herein set forth. 1
